There are people out there who have driven both over 1 million miles.

The guy driving the Tacoma needed a head gasket at 880,000 miles. Technically the engine was otherwise still OK, but he bought one from a scrapyard with 100,000 miles on it and just replaced the engine instead of reparing the one with almost 900,000 miles on it. The current engine has over 300,000 miles on it now including the 100,000 on it when installed.
And FWIW he does 10,000 mile oil changes. The original plugs were replaced at 700,000 miles and the transmission had its 1st service at 400,000. It is still going after 1.2 million miles.
My brother has an 06 Tundra, I have an 07 Tacoma. Both are right near 200,000 miles and neither of us have had any major issues. The 06 and older Tundra's have timing belts that need to be replaced at 100,000 miles. It isn't a cheap job. Starting with 2007 Tundra's they have timing chains that don't need to be replaced. I like the 1st gen Tundra, but they aren''t significantly bigger, nor will they tow more than the 2nd gen Tacoma. Plus you have to deal with timing belt changes every 100K. If I needed more room I'd look at the 07 and newer Tundra.
My 07 with a DC is a big step up in size compared to your 01 truck, but is still a little small. I reached the point 3 years ago where I needed a bigger truck. I COULD have traded my Tacoma and bought a new Tundra or F150. But it I decided I'd rather keep the Tacoma and bought a used 2014 F-150 crew cab for about the same out of pocket money. I looked for a good used Tundra, but simply never found a used one that met my criteria at a price I was willing to pay.
